A massive Danish study of over 1 million children found ZERO link between aluminum in childhood vaccines and 50 health conditions — including autism, asthma, and autoimmune diseases.

Real data. Real science. Vaccines remain safe. 📊💉

The current CDC page says that studies supporting a link between vaccines and autism “have been ignored by health authorities.” It states: “The claim ‘vaccines do not cause autism’ is not an evidence-based claim because studies have not ruled out the possibility that infant vaccines cause autism.” CDC communications staff who were first asked to post the revisions to the website were reluctant to do so without sign-off from scientific leadership, so a higher-level communications official did so, according to an agency employee and a former federal health official with direct knowledge of the matter, who spoke on the condition of anonymity for fear of retribution. The revisions show that the “CDC cannot currently be trusted as a scientific voice,” said Demetre Daskalakis, who formerly led the agency’s center responsible for respiratory viruses and immunizations. He was one of three senior leaders who resigned in August because of what they said was the politicization of science at the agency. “The weaponization of the CDC voice by validating false claims on official websites confirms what we have been saying,” he said.

CDC website changes suggesting that vaccines cause autism were made by a senior communications official without scientific leadership sign off when lower comms ppl balked

UNAids is set to close in 2026 – four years early. Are experts right to be alarmed? The move to shut the agency comes as aid budgets are being slashed, leading to fears that global progress on HIV may be reversed

“Many governments and scientists across Africa use the @unaids.org data to understand where more efforts need to be put in place... UNAIDS holds the mirror to the epidemic for everyone to see and act.”

These findings underscor...

Dengue vaccine effectiveness during outbreak in adolescents - 50.2% after first dose, 61.7% after 2nd dose, also protective against hospitalization. Protection waned to 49.7% by 90 days. For outbreak intervention, decline may be less meaningful… #IDSky

Layoffs begin at Atlanta-based CDC, other US health agencies The layoffs include 2,400 jobs at the CDC.

Several colleagues at the CDC are waking up this morning to emails notifying them they are no longer employed. A cruel purge that will cripple the agency and its mission of protecting public health.
I stand with public health.
